Methyl Formate (CAS 107-31-3) is a methyl ester of formic acid that appears as a clear colorless liquid with a pleasant ether-like odor; it serves as a solvent and blowing agent in polyurethane foam and insulation production and as an intermediate in formamide and dimethylformamide (DMF) synthesis. It is an ester formed from methanol and formic acid, notable for its high vapor pressure and rapid evaporation rate.

Methyl Formate
Applications
Used as a solvent, blowing agent, and intermediate in chemical synthesis. In polyurethane foam and insulation production, it serves as an eco-friendly blowing agent replacing CFCs. Industrially, it is employed in formamide and dimethylformamide (DMF) synthesis.
Safety & Risks
Highly flammable and mildly toxic by inhalation; avoid ignition sources and ensure adequate ventilation.
Packaging
Supplied in 180–200 L steel drums or 1,000 L IBC tanks. Store cool, dry, and tightly sealed away from acids and oxidizers.
